I know this thread is practically useless without pictures, which I don't have. But in general what would be a good price to purchase a 1983 Trek 620: Suntour Cyclone MK II components, DiaCompe 500G sidepull brakes, Reynolds 531C double-butted frame that is "well-maintained." Keep in mind this is Tucson, and old Treks don't come around very often.
